Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

A partial supernumerary umbilical vein: a case report

Journal of Medical Case Reports, 2019
Background Abnormalities in the number of vessels can be found for both the umbilical artery and vein. We sometimes encounter cases of a decreased number of umbilical cord vessels, such as a single umbilical artery.

A comparative-analysis of glycosaminoglycans from human umbilical arteries in normal subjects and in pathological conditions affecting pregnancy

, 1992
BACKGROUND: Vascular cells express different phenotypes in adult and fetal vessels, and the extracellular matrix they synthesize should reflect these differences.

Isolated Single Umbilical Artery and Histomorphometric Changes of Umbilical Blood Vessels in Intrauterine Growth Retarded Foetus in Comparison to Normal Neonates

Journal of Pharmacy and Bioallied Sciences
Background: Three vessels—one vein and two arteries—allow the fetus and placenta to exchange waste, oxygen, and nutrients in the umbilical cord. Single umbilical artery (SUA), a congenital abnormality with one umbilical artery, can occur in some ...

Pseudo-Single Umbilical Artery by Spontaneous Intrauterine Umbilical Artery Thrombosis [PDF]

Perinatology, 2019
Umbilical artery thrombosis is rare event and few prenatally diagnosed cases have been reported. Antenatal diagnosis is very critical, as it is associated with high risk of perinatal motility and morbidity such as intrauterine growth restriction and intrauterine fetal death.

The clinical significance of antenatal detection of discordant umbilical arteries. [PDF]

, 1998
Objective: To evaluate the clinical significance of the antenatally detected discordant umbilical arteries (UAs). Methods: Women with singleton gestations undergoing sonographic evaluations were examined for the presence of discordant UAs. Transverse and

Endogenous Engineering Reprograms Extracellular Vesicles for Enhanced Therapeutic Function

Advanced Science, EarlyView.
This review explains how Extracellular vesicles‐producing cells can be endogenously engineered to load therapeutic proteins and nucleic acids. We summarize physiological and genetic strategies that harness native sorting pathways for selective cargo loading.

Umbilical Artery Thrombosis Masquerading as Single Umbilical Artery in a Stillbirth

Diagnostics
Background: Umbilical artery thrombosis (UAT) masquerading as a single umbilical artery (SUA) is a rare but critical diagnostic challenge in prenatal care. Case Presentation: We described a case of a 22-year-old primigravida with an uneventful obstetric history who presented with reduced fetal movements at 22 weeks of gestation.

Lyophilized Synthetic Platelets: In Vitro Characterization and in Vivo Evaluation in Mouse Thrombocytopenia Model

Advanced Science, EarlyView.
ABSTRACT Platelet transfusions to treat bleeding complications use donor‐derived platelets stored at room‐temperature, that have a shelf‐life of only 5–7 days due to bacterial contamination risks. Cold‐stored and freeze‐dried platelets are being investigated for extending shelf‐life, but these still have the inherent challenge of donor‐dependency.
